(Cl. 28-62) This invention relates to a discovery of a new ters of reference indicate corresponding parts in and useful method or process, having for its genall views, and in which:- eral object to provide different kinds of yarn, as, Figure 1 illustrates a yarn, or chenille in its for instance, a chenille, cords, and threads of an usual and ordinary marketable form; while Fig- 5 exterior flufiiness, with a surface that may be ure 2 is a cross sectional view of same. 1 54) varied in form, character and appearance, 9.0- Figure 3 shows a chenille, which has been subcording to the special treatment applied thereto. mitted to a treatment, according to this inven- As stated, generally most kinds of yarn may tion; and Figure d is a cross section of Figure 3. form the subject matter of such a treatment, Figure 5 is a longitudinal sectional view of a 1 whether the said yarn consists of a woolen, wortube with a smooth inner surface, as used in this sted cotton, rayon, or any other material.

so with the above and other objects in view, this The said tubes are heated preferably by elecinvention consists of the novel features, combltricity, and in a manner similar to that employed nation of steps and relevant construction, as in flatirons; thus Figure 5 shows an electric conhereinafter fully described, claimed and illustact 11, for the purpose of conveying heat to the trated in the accompanying drawing forming part said tube.

" of this application, and in winch similar charac The yarn in its ordinary form is brought in contact with the heating medium, or, as herein illustrated especially in Figure 9, a tube; and the said yarn is held in close proximity to or retained in and by the said tube a short length of time, for instance a few minutes, the said time naturally to be varied according to the purpose at hand and the amount of heat applied thereto.

when the yarn or chenille enters the said tube the outer ends of its fibres contact with the inner surface of the tube and usually the said yarn or chenille is then submitted to a back and forward movement for a very short length of time, whereby the said yarn upon leaving the tube, as shown in Figure 7, has received a surface with a solid impression, form, or a pattern, made thereon by means of the said exposure to heat in conjunction with the said contact of its fibres with the specially formed inner surface of the tube.

The object thus achieved is the result of the fibres of the yarn contacting with the inner surface of the tube and of the simultaneous exposure to heat thereof. The said yarn may thus receive an appearance of, for instance. a swirled or curled form, according to the prearranged design of the said irmer tube-surface.

Referring to the feeding of the yarn to the said tube and the relative back and forward movement of the former, this may be accomplished by hand made to'move back and forth in the said tubes. the latter may be made to perform this action, while the yarn may remain stationary.

It is obvious that changes may be made in the form, construction and arrangement, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not therefore desire to limit myself to the manner, construction and arrangement shown and described herein.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. A means for imparting to a yarn a special form, comprising a heated tube, movable back and forth, the said tube being formed with a threaded inner surface.

2. A means for imparting to a yarn a special form, comprising a heated tube, movable back and forth, the said tube being formed with an inner surface threaded at intervals.

3. A means for imparting to a yarn a special form, comprising a heated tube, movable back and forth, the said tube being formed with a knurled inner surface.

4. A means for imparting to a yarn or chenille a special form, comprising a heated tube formed with athreaded inner surface and adapted to permit a back and forth movement of the said yarn therein.
